摘要 |
First-principles calculations allow us to understand the electronic and magnetic properties of real materials in terms of their chemical composition, atomic structure and magnetic configuration by numerically solving the quantum mechanical equations that describe the motion of the electrons. In this talk, I review a first-principles scattering formulation of quantum transport that has been used to study resistivity, spin-flip diffusion, Gilbert damping and spin torque in a wide range of magnetic heterostructures that form the active parts of spintronics devices. By simultaneously including spin-orbit coupling, noncollinear magnetization and temperature-induced disorder, I demonstrate how we are able to identify novel properties arising from the interplay of these effects. |
